After i add a section and create a wrap and an item, after i "Update" , all the changes are gone and remain the same. Same as when i want to update the details on existing picture, it totally not function.
There is very simple test. Please create php file with phpinfo() function inside, send us link to that file and we will proof that you didn't changed anything.
